Answer:

Alluvial fans are evidence that the Death Valley is a tectonically active region.

Explanation:

  • Alluvial fans can be only formed by the slow and gradual depositional action of a river.
  • But for an alluvial to be formed, it is primarily necessary for the river to continuously carry and deposit sediments for a long period of time.
  • The supply of sediments done by the Death Valley in California provides evidence that it is a tectonically active region.
